The final version of GO Dizzy GO hack is at last here!
Aim of the hack is to increase difficulty level of gameplay.Hardcores will be happy now
Biggest news in this version is all new levels and bonus levels.
There's a hidden tricks in some levels to make game a little easier.Like moving box,so item can appear(items can't appear in block).
Here's a changes log:

-Dizzy walking speed increased by 15%

It's last version of hack(I'll make 1.0+ if there's some thing need to fix)Great Thanks to Siloucos for making great,hard and funny Dozy world levels and bonuses.
I also need to thank Micrus for creating WinGDG,without it this version of hack wouldn't have new levels and bonuses!

Hey.
I like both Go Dizzy(I prefer NES version) and CJ antics.
You said you have lots of data about dizzy games,maybe, by chance, you have something about CJ?
Ahhh,and I tried this hack.
It's too hard to get farther than 3 world...
Anyother hack will be created?

Sorry for...umm, very long response time.
Yes, I plan to make another hack when Armacoder and I finish WinGDG(Go Dizzy Go editor) and it's function for GDG Expand ROM.Expand will give a variety of options like changing graphics, paletes and even(still not sure..) music!
About CJ-It's pretty problematic, Levels have compression, graphics have compression, and enemies format is strange.
With this, I don't plan any hack of CJ.
